Abstract
This paper proposes a wireless approach for water-level monitoring and control-system using standard wireless transceiver module HC-12 in a legal frequency band of 433.4 MHz to 473.0 MHz supported with hundred communication channels. The monitoring and control range is up to 500 meters in open-air and about 100 meters indoor. The microcontroller Arduino ATMEGA328 is used as monitoring and controlling device. The module is set initially for the baud-rate of 9600, 20 dBm transmitting power, -112 dBm receiving sensitivity, 445 MHz transmission frequency and channel number 50. All the modules in the network are set to the same parametric values to achieve synchronized communication. The controlling program collects the information regarding water-levels in different tanks and initiates control action as to start or stop the water pumping motor. It also displays the status of the water levels in different tanks. The design is tested for the household purpose. To achieve long range communications, the LORA modules could be used but for higher cost- Article View: 118
